Numerical Analysis on the Collapse of a RC Frame

Abstract

This paper focuses on the collapse analysis of a planar RC frame. This research is based on an experimental study presented in the literature. The analyses are conducted using a dedicated software based on the Applied Element Method. This numerical method is able to model accurately all the structural behaviour stages leading up to the collapse itself. A very good match between the experimental and numerical results is observed. The numerical investigation highlights several behaviour stages for the model RC frame. Moreover, the contribution of the RC slab and the impact of the concrete strength on the overall collapse mechanism is discussed and evaluated through numerical investigation.

“…Several numerical studies have been conducted to verify the accuracy of prediction of this method in the real world collapse cases of multi storied buildings [19,20]. Comparisons have also been made in the cases of extreme deformations and collapses with other established methods and the method could effectively represent various stages of structural deformations up to collapse itself [21,22]. The method is extensively used in seismic assessment of buildings [23].…”
